TOOL FR FINISHING SHOE-SOLES.

To all whom z' may concern.'

Be it known that I, FRANKLIN O. THOMP- soN, a citizen of the UnitedStates, residing at Meredith, in the county of Belknap and State of NewHampshire, have invented a new and useful Tool for Finishing Shoe-Soles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledinthe` art to which it appertains to make and use the same.

This invention relates to a new and useful shoemakers tool.

As one of the objects of the invention, it is the aim to provide a toolof this nature, which may be operated by any suitable power (not shown),which is adapted to be belted to the operating shaft of the tool.

A further object of the invention is the provision of such a tool forburnishing and finishing the heels, shanks, edges, and the bottoms ofboots and shoes and the like.

Another object of the invention is to heat the burnishing parts of thetool by friction.

In the drawings are disclosed certain features of construction, but inpractical fields these features may necessitate alterations, to whichthe patentee is entitled, provided the alterations are comprehendedwithin the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed..

In the drawings Figure 1 is a view in elevation of the improvedshoemakers tool constructed in accordance with the invention. Fig. 2 isa longitudinal sectional view. Fig. 3 is a transverse sectional view.

Referring more particularly to the drawings 1 designates a shaft, towhich power may be furnished by any suitable means, such as gearing orbelting (not shown), in order to rotate the tool. This shaft is providedwith a spline seat or groove 2, which receives the shank of the setscrew 3 carried by the sleeve 4, so as to cause the sleeve to rotatewith the shaft 1. One end of the sleeve is provided with an annularenlargement 5, from the periphery of which an annular fiange 6 projects.Between the outer circumference of the sleeve 4 and the flange 6 anannular space 7 is formed, in which the coil spring 8 is seated.Partially telescoping the flange 6 is a sleeve 9,-the outer end portionof which terminates in ,an enlarge- Specification of Letters Patent.

ment 10 having a beveled periphery 11, and provided with an annulargroove 12.

Fitting on the shaft 1 beyond the sleeve 4 is a collar 13, which isformed or constructed with a spline seat or slot 14, into which thespline screw 15, which is threaded in the enlargement 10, eXtends, so asto cause the ,y collar 13 and sleeve 9 to rotate as one.

The bevel 11 constitutes means to assist in burnishing and finishingshoe soles, that is, l one of the edges thereof, while the beveled=surfaces 16 assist in finishing and burnishing the other edge of thesole, whereas the bead or ridge between the bevels 16 forms orconstructs a slight depression in the sole of the shoe, in order to makea line of demarcation between the welt of the shoe and the sole. Thebevels 16 are constructed on a disk 18, and the bead or ridge is denotedby the character 19. This disk 18 is provided with an extension 20, tobe received by the collar '13, and extending through the disk and theextension is a screw 21, which is threaded into the shaft 1 of the tool,so as to cause the disk 18 to rotate with the shaft. In this manneralso, owing to the fact that the disk 18 engages the collar 13, saidcollar is firmly clamped between the disk 18 and the sleeve 4. In thismanner it will be seen that the collar 13, the disk 18 as well as thesleeve 4 all rotate substantially with the shaft 1, and by arranging orholding the edge of the shoe sole between the bevels 11 and 16, theproper burnishing and finishing may be imparted to the shoe sole. In s0doing the bevel 11 of the enlargement 10 of the sleeve 9 bears yieldablyagainst the edge of the sole of the shoe, as will be seen in thedrawings, owing to the fact that the coil spring is interposed betweenVthe enlargements 5 and 10. When motion is imparted to the shaft 1 byany suitable power, whether by hand or otherwise, preferably belt-ing orgearing, and the tool is correspondingly operated, a metal finger, suchas that indicated in the drawings and adapted to be held stationaryenters the groove 12, and by a frictional contact therein, the entireenlargement 10, and especially the bevel 11 becomes highly heatedthrough friction.

Having set forth the invention, it is to be noted there has been deviseda novel construction of shoemakers tool, and one which has been foundparticularly desirable and practical.

The invention having been set forth, what is claimed as new and usefulis l.' In combination, a revoluble shaft having a burnishing andfinishing tool revoluble therewith, the tool having a yieldable memberprovided with an annular groove, into which a device extends, wherebyfrictional heat is generated as the tool revolves.

2. In combination, a revoluble shaft, a

sleeve including an enlargement having a ment and a portion of themember, and a device extending into the groove to generate frictionalheat in the member when rotating.

3. In combination, a revoluble shaft, a disk revoluble therewith andprovided with a beveled periphery having a bead, a yieldably mountedmember having connections with the shaft in order to rotate therewithandprovided with aV beveled surface between which and the beveledperiphery of the disk the edge of a shoe sole is adapted to be arranged,for burnishing and finishing the same, and means for generatingfrictional heat in the yieldably mounted member.

In testimony whereof I have signed my a name to this specification inthe presence of two subscribing witnesses.
